FRANK E. MODLIN, OF FORT WORTH, TEXAS.

GAS-PRODUCER.

Specification of Letters Patent.

Patented Feb. 25, 1919.

Application led June 1, 1918. Serial No. 287,747.

To all whom t may concern Be it known that l, FRANK E. Monmn, a citizen of the United States, residing at Foi-t Worth, in the county of Tarrant und Stato of Texas, have invented u new und useful (las-Producer, of which the following is a specicatiou.

This invention relates lo gus producers, and contemplates the provision of a structure for the production of.' gus which will be simple, durable, dnd eilicient in operation.

erniitting the use of cheap fuel, such ns lignite, in. the manufacture of gas.

A main object of the invention is the -provision of means for convertingr by-products, such as coal-tar and creosote, into gas.

Another obj ect of the invention is the provision of means for feeding the fuel evenly to the fire bed. A

A still fur-ther object is theiprovision of a Superheater for the gas.

With the foregoing and other objects in view which will appear as thc description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter dc scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed Without deport ing from the spirit of the invention.

A practical embodiment of the invention is shown in the accompanying drawings, wherein Figure 1 is a oentraltvertical section of a producer constructed in accordance with the invention;

Fig. 2 is a cross section on the line 2-2 of Fig. 1, viewed in the direction of the arrows;

Fig. 3 is a section on the line 3-3 of Fig. l;A

ig. 4 is a plan view of the superheater; Fig. 5 is a central cross section of the same. r

Referring to the drawings by numerals of reference y ,In carrying out lthe invention there is provided a base section or drum 1 which forms an ash pit and draft chamber, afi which is provided with an opening not lnally closed by the usual ash and draft door 2. A girate 3 of any usuel and preferred type is supported on the drum 1.

Seated upon'the drum 1 is an upright,

double Walled drum 4 the spaced inner and outer walls of which provide a water space 5 for the purpose of protection. This drum 4 constitutes the fire pot and collection chamber or retort of the device.

Depending within the drum 4 and spaced vfrom the inner wel] thereof, is an inverted truste-conical tubular feeder 6 the lower end of the wall of which is formed with radially disposed out-struck hoods 7 which communicate with the interior of the tubuv lar feeder. The lower end of this feeder terminates just above the fire bed and its upper end is secured by rivets or otherwise to the annular supporting member 8, formed with an outturned ange 9 which flange rests upon a ring 10 seated on the drum 4 and through which ring the :innu-` lar support Sprojects.

A tu ular container 11 has its lower end threaded into or otherwise secured to the support 8 and its upper end is formed with a flaring mouth or hopper 12. The container 11 is provided with spaced transverse slots through which slide the upper and lower gates 13 end 14, respectively. The upper gate 13 is formed with a rudinlliY extending ear which has pivotal attachment. to a bracket 15 secured to the side of'the container 11. At a diametrically opposed point, a radially extending* handle 16 is formed on the gate 13. The lower gate 14 is also provided with s similar ear which has Apivotal attachment to a bracket 417, and the gate is likewise provided with a handle 18. The handles 16 and 18 allow the upper and lower gates to be successively swung to admit charges of fuel to the lower portion of the container 11.

An annular worm wheel 19 encircles the lower end of the container 11, to which it is rigidly secured, and meshes with a Worm 2O which is driven by any suitable means (not shown) for the purpose of rotating the container and the feeder 6.

Pipes 21; communicate at suitable intervals with the interior of the drum 4, near the upper end of said drurn, and converge downwardly about bthe outside of the drum to take into one end of a super-heater 22 which is horiz-ontallyvjarrangcd above theA grate 3 and in position tobe embedded in the ire'bed. The super-heitter` 22 is preferablylfomedf with shortj: cylindrical ends between which ends it isjettened to' form ings or ports of the union 24, rises from the union and within this cylinder is a 'centrally disposed rod 27 which extends longitudinelly of the cylinder, and on which are secured the spaced, conical disks 28 formed with apertures 29. A collar 3() is threaded on 4the upper end of the cylinder 2G and is closed by a plug 3l which permits access to the cylinder for the purpose of removing the rod 27 and its disks, when the saine becomes necessary. An inlet pipe 32 leads through an aperture in the collar 3() and conveys a suitable stream of water to the cylinder, which water, dropping through the ap` ertures 29, tends to wash the ascending gas.

After passing through the cylinder 2() and being washed and cooled, the gas passes through a pipe 36 which is threaded into the collar 30 to a receiving tank or storage tanki 37, from which it may be led to an)Y desired point through a pipe 38.

The wash water, after passing through the cylinder 26 and removing the impurities -from the gas, passes through a pipe 35S which is threaded into the union 24 and deponds therefrom, -to a trap 34 from whence it is conducted by an overdow pi pe 35 to thc usual sump or the like.

In practice the device is operated in the following mannen- Fuel is fed to the container 11 through the liqp er 12 and, as the fuel is consumed. a ft s charge is delivered to the container by swinging the upper gate13 open to allow fuel to ll the space between the upper and lower gates. The upper gate is then closed and 'the lower gate opened allowing the charge of fuel to gravitatc to the lower end of the container.

A fire havin been Started in the grate 3 to ignite the fue the worm 2O is rotated, imparting rotation to the (xintaner 1l and feeder 6. Fuel will then gravitate from the. container 11 to the feeder 6 and from the central opening in the feeder 6 .and through the hoods 7 tothe lire bed. Because of the rotary motion of the feeder, the fuel will bc distributed 'by the hoods evenly over the fire, bed.

Gases rising from the fire will be trapped in the upper portion of the drum 4 from whence they will pass through the. pipes 2l to the super-heater 22. The intlinse heat'ot' the super-hcater will thoroughly dry tlir4 green gas and will gasify any particles of coal-tar or ereosote which may be contained in the gas and find its way through the pipes into the super-heater. f

From the super-heater 22 the gas is ron ducted through pipe 23 to the washer, as hereinbefore set forth.

Having thus described the invention` what is claimed as new and sought by Letters latent, is r 1. A gas producerembodying a dxuml providing a fire pot and a retort, means for feeding fuel to the, drum, a super-heater arr ranged in the lower portion of the drum and adapted to be buried in the fire, bell, means for conducting gas from the upper portion of the drum to the su|er-he.-1ter. and means for conducting the gas from the super-heater.

2. A gas producer en'ibod'ring u drum pro riding a fire pot and a retort', a grate., ilu-.ans for feeding fuel to the, drum, a super-heater arranged in the lower portion of the drum and buried in the fire bed on the grate` said super-heater being parallel with the. grate, means for conducting gas from the upper portion of the. drum to the sumar-heater, and means for conducting -fthe gas from the super-imiter. f

3. A gas producer embodying), a drum providing a fire pot and retort, means for feedw ing fuel to the drum, a super-heater ai ranged in the lower portion of the drum and consisting of a flattened tubular member b1|ricd in thtl fire bed, means for conducting gas from the upper portion of the drum to ,the super-heater, and means for conducting the gas from the super-heater.

4, A gas producer embodying a drum providing a fire pot and a retort, means for feeding fuel to the drum, a grate, a superlieatcr having a restricted passage and arranged in the lower portion of the drum and parallel to the gra-te, means for conducting gas from `the upper portion oi" the drum to the eimer-heater, means for conducting the gas from the super-heater, and means for washing the gas.-

ln testimony that I claim the, foregoing as my own, I have hereto affixed my signa.-
